Safe Isolation & Voltage Indication

Safe isolation procedures are in place to protect users from death when carrying out work on electrical circuits.

Electrical Safety First recommends locking off circuits, using dedicated lock out devices (also known as lockout-tagout, or lock and tag) and also proving a circuit is dead with the use of a two pole voltage indicator.

Our range of lock off kits, voltage indicators and proving units will make sure you have the right test equipment to ensure your safety.
